BACKGROUND

Amla (or Amlaka, Amlaki, or other variants) is one of the most frequently used of the Ayurvedic herbs; it is the fruit of Phyllanthus emblica, also called Emblica officinalis. The fruit is similar in appearance to the common gooseberry (Ribes spp., a type of currant), which is botanically unrelated to amla. However, due to the similar appearance of the fruit clusters, amla is usually called the “Indian gooseberry.” The plant a member of the Euphorbiaceae, grows to become a medium-sized tree that is found growing in the plains and sub-mountain regions all over the Indian subcontinent from 200 to nearly 2000 meters above sea level. Indian gooseberry is a wonder herbs and one of the precious gifts of nature to man. It contributes towards health and longevity.

Emblica officinalis (EO) enjoys a hallowed position in Ayurveda—an Indian indigenous system of medicine. According to ancient Indian mythology, it is the first tree to be created in the universe. Emblica officinalis fruit is one of the key constituents of the celebrated Ayurvedic preparation, Chyavanaprash, used in India for thousands of years as a vitalizing and rejuvenating health tonic. According to Ayurveda, amla balances all three doshas. While amla is unusual in that it contains five out of the six tastes recognized by Ayurved, it is most important to recognize the effects of the “virya”, or potency, and “vipaka”, or post-digestive effect. The fruits of EO are widely used in the Ayurveda and are believed to increase defense against diseases. I

Coronary heart disease (CHD) continues to be the major cause of premature death in most developed and developing countries. A low level of HDL cholesterol is the second most important risk factor for CHD, as demonstrated in numerous clinical and epidemiological studies (Gorden, D. and Rifkind, H. M., N. Engl. J. Med., 1989, 321:1311-1315; Brewer, Jr., H. B. New Engl. J. Med, 2004, 350:1491-94) and HDL has emerged, during the past decade, as a new potential target for the treatment of cardiovascular diseases. The key role of HDL as a carrier of excess cellular cholesterol in the reverse cholesterol transport pathway is believed to provide protection against atherosclerosis. In reverse cholesterol transport, peripheral tissues, for example, vessel-wall macrophages, remove their excess cholesterol through the ATP-binding cassette transporter 1 (ABCA1) to poorly lipidated apolipoprotein A-I, forming pre-.beta.-HDL. Lecithin-cholesterol acyltransferase then esterifies free cholesterol to cholesteryl esters, converting pre-β-HDL to mature spherical α-HDL.

HDL cholesterol is transported to the liver by two pathways: 1) it is delivered directly to the liver through interaction with, the scavenger receptor, class 8, type 1 (SR-B1); 2) cholesteryl esters in HDL are transferred by the cholesterol ester transferase protein (CETP) to very-low-density-lipoproteins (VLDL) and low-density lipoproteins (LDL) and are then returned to the liver through the LDL receptor. HDL cholesterol that is taken, up by the liver is then excreted in the form of bile acids and cholesterol, completing the process of reverse cholesterol transport (Brewer, H. B. Jr., Arierioscl. Thromb. Vasc. Biol., 2004, 24:387-91). HDL is believed to have the ability to remove cholesterol from macrophages, thus preventing the formation of foam cells.

A second beneficial role of HDL in atherosclerosis is in protecting LDL from oxidation (Navab, M. et al, Circulation, 2002, 105:290-92). Unlike normal LDL, oxidized LDL is readily taken up by macrophage scavenger receptor SR-A or CD36 resulting in the formation of foam cells. Foam cells are a major component of the early atherosclerotic lesion. Further, HDL may slow the progression of lesions by selectively decreasing the production of endothelial cell-adhesion molecules that facilitate the uptake of cells into the vessel wall (Barter, P. J., et al, Curr. Opin. Lipid, 2002, 13:285-88). HDL may also prolong the half-life of prostacycline and preserve its vasodilators' effect (Mackness, M. I. et al, Atherosclerosis, 1993, 104:129-35).

Several lines of evidence support, the concept that increasing the HDL level may provide protection against the development of atherosclerosis. Epidemiologic studies have shown an inverse relation between HDL cholesterol levels and the risk of cardiovascular disease. Increasing the HDL cholesterol level by 1 mg may reduce the risk of cardiovascular disease by 2 to 3 percent. Over expressing the apo-A-I gene in transgenic mice and rabbits and infusing complexes consisting of apo A-I and phospholipids into hyperlipidemic rabbits increase HDL cholesterol levels and decrease the development of atherosclerosis (Brewer, H. B, Jr., loc. cit). In humans, infusing either of these complexes or pro-apo-A-I results in short term increase in HDL cholesterol, biliary cholesterol and fecal cholesterol loss, reinforcing the concept that elevating the HDL cholesterol level decreases the risk, of cardiovascular disease.

More than 40 percent of patients with myocardial infarction have low HDL-C as a cardiac risk factor. (Genest, J. J., et al, Am. J. Cardiol, 1991, 67:1185-89). In the prospective and multicentric European Concerted Action on Thrombosis and Disabilities (ECAT) Angina Pectoris Study, Bolibar et al (Thromb. Haemost, 2000, 84; 955-61) identified low HDL-C and low apoA-I as the most important biochemical risk factors for coronary events in patients with angiographically assessed CHD. By convention, the risk threshold value of HDL-C has been defined as 35 mg/dL (0.9 mmol/L) in men and 45 mg/dL (1.15 mmol/L) in women [Expert panel on detection, evaluation and treatment of high blood cholesterol in adults. The second report of the National Cholesterol Education Program (NCEP) expert panel on detection, evaluation and treatment of high blood cholesterol in adults (Adult Treatment Panel II). Circulation. 1994; 89:1329-1445)]. Because of interaction, the strength of the association between HDL-C and cardiovascular risk depends on the presence of additional risk factors. Therefore, threshold values are higher in men with diabetes mellitus or hypercholesterolemia or in the presence of multiple risk factors (von Eckardstein A, and Assmann G. Curr Opin Lipidol. 2000; 11:627-637). Low HDL-C has been identified as the most frequent familial dyslipoproteinemia in patients with premature myocardial infarction (Genest, J. J. Jr., Circulation. 1992; 85:2025-2033). Finally, in the Helsinki Heart Study (Manninen, V. et al, Circulation. 1992; 85:37-45) and the High-Density-Lipoprotein Cholesterol Intervention Trial of the Department of Veterans Affairs (VA-HIT) study (Rubins, H. B. et al, N Engl J Med. 1999; 341:410-418), increases of HDL-C on treatment with gemfibrozil were correlated with the prevention of CHD events. Thus, HDL-C has become an important component of algorithms to assess the global cardiovascular risk of patients and also a target for therapeutic intervention and for the definition of treatment goals.

Strategies to correct dyslipidemia in atherosclerosis generally involve diet and/or drugs. The threshold serum tote cholesterol and LDL cholesterol concentrations above which diet and drug therapy should be initiated, as well as the goals of therapy, have been defined by the National Cholesterol Education Program (JAMA, 1993, 269:3015-23). The target serum LDL-C is <160 mg/dl (4.3 mmol/l) for patients with no risk factors or only one risk factor for CHD; <130 mg/dl (3.4 mmol/l) for patients with 2 or more risk factors and less than 100 mg/dl (2.6 mmol/l) for those with CHD. Persons with diabetes also fell into the third category. A reasonable target for triglyceride concentration is 200 mg/dl or less; higher values are associated with a doubling of the risk of cardiovascular disease when serum cholesterol concentration exceeds 240 mg/dl or when the LDL-C/HDL-C ratio exceeds 5:1.

A number of studies have shown that reducing serum LDL-C below the target levels does not necessarily result in proportional reduction in the risk of CHD [(The Scandinavian Simvastatin Survival Study Group. Randomized trial of cholesterol lowering in 4444 patients with coronary heart disease, Lancet, 1994, 344:1383-89; Shepherd, J. et al, N. Engl. J. Med., 1995, 333:1301-7; Sachs, F. M. et al, N. Engl. J. Med., 1998, 315:1001-9; Circulation, 1998, 97:1446-52; The West of Scotland Coronary Prevention Study Group, Circulation, 1998, 97:1440-45; Pederson, T. R., Circulation, 1998, 97:1453-60] because of the attenuation of the cholesterol-heart disease relation at lower serum, cholesterol concentrations (Grundy, S. M., Circulation, 1998, 97:1436-39).

Dietary treatment of hyperlipidemia is a necessary foundation for drug treatment. Depending on the degree of hyperlipidemia, the Step I and Step II diets can be introduced sequentially. The Step II diet contains no more than 30% of calories from fat, less than 7% of calories from saturated, fatty acids and less than 200 mg of cholesterol per day. In long term studies, the Step II diet decreased serum LDL-C concentrations 8-15% (Knopp, R. H., et al, JAMA, 1997, 278:1509-15; Walden, C. E., Arterioscl. Thromb. Vasc. Biol, 1997, 17:375-82; Denke, M. A., Arch. Intern. Med., 1995, 156:17-26). Diets more restricted in fat than the Step 11 diet result in little additional reduction in LDL-C, raise serum TG concentration and lower HDL-C.

The point to note, from the above, is that reducing LDL-C alone is of little value in reducing the risk of CUD. Further, diets meant for reducing LDL-C may reduce HDL-C to a similar degree (Hunninghake, D. B. et al. N. Engl, J. Med., 1993, 328:1213-19; Schaefer, E. J., et al, Arterioscl. Thromb. Vasc. Biol, 1995, 15:1079-85); Stefanick, M. L., N. Engl. J Med. 1998, 339:12-20).

Drug therapy is resorted to when the desired effects are not achieved with diets alone. Statins are the most popular among the lipid lowering drugs. These drugs lower serum LDL-C concentrations by upregulating LDL-receptor activity as well as reducing the entry of LDL into the circulation. The maximal reductions achieved with a statin ranges from 24-60%. Statins also reduce the serum TG levels; but they are often insufficient. Statins are ineffective in the treatment of patients with chylomicronemia. Adverse effects of statins include, gastrointestinal upset, muscle aches and hepatitis. Rarer problems include myopathy (muscle pain with serum creatine kinase concentrations more than 1,000 U per litre), rashes, peripheral neuropathy, insomnia, bad or vivid dreams and difficulty in sleeping or concentrating (Abramowica, M., Med Lett., 1996, 38:67-70; Vgontzas, A. N. et al, Clin. Pharmacol. Ther., 1991, 50:730-37; Roth, T. et al, Clin. Cardiol., 1992, 55:426-32; Partinen, M. et al, Am. J, Cardiol., 1994, 73:876-80). Other lipid-lowering drugs include bile acid-binding resins (e.g. cholesteramine and colestipol), nicotinic acid, and fibrates.

Drug therapy is not recommended for premenopausal women and men under 35 years of age unless they have serum LDL-C concentrations of more than 220 mg/dl (5.7 mmol/l), because their immediate risk of heart disease is low [Summary of the second report of the National Cholesterol Education Program (NCEP); expert panel on detection, evaluation and treatment of high blood cholesterol in adults, JAMA, 1993, 269:3015-23].

Thus, diets alone or in conjunction, with lipid lowering drugs fail to yield the desired goal of safe lipid lowering. However, this goal is achievable with the present inventive composition containing the active principles of seed of Emblica officinalis. Emblica has been in safe use in India for thousands of years as component of Ayurvedic preparations. The composition from seed of Emblica officinalis offers the twin benefits of reducing the harmful LDL cholesterol and enhancing the desirable HDL cholesterol.

A number of studies have shown that Emblica officinalis is useful for reducing total cholesterol, reducing triglyceride, reducing LDL cholesterol and enhancing HDL cholesterol.

Ritu Mathur et al show the hypolipidaemic effect of fruit juice of Emblica officinalis in cholesterol fed rabbits. The juice is obtained from deseeded Emblica officinalis. U.S. Pat. No. 6,124,268, Ghosal discloses a natural antioxidant composition from Emblica officinalis using pericarp of fresh berries (Emblica officinalis). Bis was Gopa et al show the hypolipidemic efficacy of Amla (Emblica officinalis). The Amla used is dried Amla fruit juice powder. Muhammed et al evaluated the anti-hyperglycemic and lipid-lowering properties of Emblica officinalis powder in normal and diabetic human volunteers. Zhang et al discloses the phenolic constituents of Emblica officinalis juice. Chatterjee et al discloses a novel compounds with hypocholesteremic activity from crude Embilica officinialis (EO) fruit extracts. U.S. Pat. Nos. 7,780,996, 8,158,167 and 8455020 discloses the method of reducing cholesterol method of treating dyslipidemia and method of reducing triglyceride by extract of Emblica officinalis.

Amla is a fruit with wide range of medicinal properties. Our effort was to find the most bioactive molecule/(s) or purified fraction having bioactivity from Amla fruit. The fleshy part (pericarp) of Amla fruit is used for human consumption whereas Amla seeds are not edible and discarded. We evaluated different Amla extracts. Extracts prepared from fresh fruit of Amla; fruit juice of whole Amla including the fleshy part and seeds of Amla; juice of fleshy part (pericarp); dried fruit; flesh of Amla fruit without seed; or Amla seed alone were evaluated for and hypolipidemic activity. The methanol extract of all groups showed beneficial activity, but the most unexpected and superior result was obtained from the Amla seed alone extract.

Amla seed alone extract was able to significantly reduce the total cholesterol, LDL cholesterol, triglycerides, VLDL cholesterol and enhance the HDL cholesterol levels. Though Amla seed is not known to have any history of human consumption, we followed the lead with various extracts of Amla seed and found that the ethyl acetate portion of Amla seed extract is the most active. The ethyl acetate part was showing far superior activity compared to other extracts with Amla seed and also against other extracts of Amla.

In view of the above, the disclosure provides a composition and method of preparing an extract from the seed of Emblica officinalis unlike other references where the extract is prepared from Emblica officinalis especially from its fruits which found its application for the treatment of reducing bad cholesterol, dyslipidemia and for reducing triglyceride.

The animals were deprived of food for next 24 hours but had free access to water ad libitum. After 24 hour of drug treatment 2 ml blood samples were collected from the retro orbital plexus. The blood was allowed to clot and then centrifuged at 3000 rpm for 10 min and the scram was carefully drawn and collected into separate tubes. The serum was analyzed for total cholesterol, triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) levels using auto-analyzer.

Results indicated that before treatment the baseline value of total cholesterol, triglyceride, HDL, LDL and VLDL in all groups were comparable, injecting Triton alone (Group II) significantly increased the total cholesterol, level to 265.6 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, cholesterol level was 120.87 mg/dl which was 2.2 times lower as compared to triton alone group.

In group II triton injection increased the triglyceride level to 692.7 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, triglyceride level, was 152.23 mg/dl which, was 4.5 times lower as compared to triton alone group.

In triton alonegroup after triton injection the ratio of HDL to total cholesterol was 0.18. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, the ratio of HDL cholesterol to total cholesterol was 0.39 which, was 2.2 times higher as compared to triton alone group.

In group II triton injection increased the LDL level to 77.59 mg/dl. Whereas in Group III, simultaneous oral administration, of Amla seed extract in triton injected rats, LDL level was 43.15 mg/dl which was 1.8 times lower as compared to triton alone group.

In group II triton injection increased the VLDL level to 138.55 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, VLDL level was 30.44 mg/dl which was 4.6 times lower as compared to triton alone group.

The standard drug Atorvastatin was also effective in lowering the cholesterol as well as triglyceride level. These results clearly indicate the hypolipidemic activity of Amla seed extract in Triton induced hypolipidemic in rats.

Example 19 Hypolipidemic Activity of Amla Seed Extracts in Different Doses Using Triton WR 1339 Induced Dyslipidemia Model

Sixty male Albino rats (Sprague Dawley strain) weighing approximate 0.250-300 gm were selected for the study. The animals were kept in the animal house maintained at temp 24±2° C., 65% relative humidity and 12 hr light/dark cycle. The rats were acclimatized for two weeks and during this period they had access to standard pellet diet and water ad libitum. After two weeks of acclimatization, all the rats were fasted overnight before injecting Triton WR 1339 (Tyloxapol) and administration of test extracts/standard. The animals were divided into ten groups. Following treatment was given to overnight fasted rats:

Group I: Normal control (vehicle only) Group II: Triton WR 1339 (300 mg/kg, intraperitoneal) Group III: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (10 mg/kg, per oral) Group IV: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (7.5 mg/kg, per oral) Group V: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (5 mg/kg, per oral) Group VI: Triton WR 1339 (300 rug/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (2.5 mg/kg, per oral) Group VII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (2 mg/kg, per oral) Group VIII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (1 mg/kg, per oral) Group IX: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepare as per example 1 (0.5 mg/kg, per oral) Group X: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Atorvastatin (10 mg/kg, per oral)

The animals were deprived of food for next 24 hours but had free access to water ad libitum. After 24 hour of drug treatment 2 ml blood samples were collected from the retro orbital plexus. The blood was allowed to clot and then centrifuged at 3000 rpm for 10 min and the serum was carefully drawn and collected into separate tubes. The serum was analyzed for total cholesterol, triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) levels using auto-analyzer,

Results indicated mat intraperitoneal injection of Triton significantly increased the total cholesterol level about 2 times over the baseline value. Similarly, triglyceride level also increased to very high level (Group II) following Triton injection. Simultaneous oral administration of various doses of Amla seed extract in triton injected rats lowered the cholesterol increase to almost normal level (Group III to IX). Triglyceride level was also lowered by all the doses of Triton with amla seed extract as compared to Triton alone group. The standard drug Atorvastatin was also effective in lowering the cholesterol as well as triglyceride level (Group X). These results clearly indicate the hypolipidemic activity of Amla seed extract at various dose levels in Triton induced hyperlipidemia in rats.

Example 20 Hypolipidemic Activity of Amla Seed Extract Compared with Other Amla Extracts Using Triton WR 1339 Induced Dyslipidemia Model

Forty eight male Albino rats (Sprague Dawley strain) weighing approximate 250-300 gm were selected for the study. The animals were kept, in the animal house maintained at temp 24±2° C., 65% relative humidity and 12 hr light/dark cycle. The rats were acclimatized for two weeks and during this period they had access to standard pellet diet and water ad libitum. After two weeks of acclimatization, all the rats were fasted overnight before injecting Triton WR 1339 (Tyloxapol) and administration of test extracts/standard. The animals were divided into eight groups. Following treatment was given to overnight fasted rats:

The animals were deprived of food for next 24 hours but had free access to water ad libitum. After 24 hour of drug treatment 2 ml blood samples were collected from the retro orbital plexus. The blood was allowed to clot and then centrifuged at 3000 rpm for 10 mm and the serum was carefully drawn and collected into separate tubes. The serum was analyzed for total cholesterol, triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) levels using auto-analyzer.

In this study, effectiveness of Amla seed extract (2.5 mg of extract/kg of subject) was compared with other amla extracts made as in Examples 3 to 6.

Results indicated that before treatment the baseline value of total cholesterol triglyceride, HDL, LDL and VLDL in all groups were comparable. Injecting Triton alone (Group II) significantly increased the total, cholesterol level to 348.87 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, cholesterol level was 112.23 mg/dl which, was 3.1 times tower as compared to triton alone group.

In group II triton injection increased the triglyceride level to 614.21 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, triglyceride level was 95.88 mg/dl which was 6.4 times lower as compared to triton alone group.

In triton alone group after triton injection the ratio of HDL to total cholesterol was 0.14. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, the ratio of HDL cholesterol to total cholesterol was 0.42 which was 3 times higher as compared to triton alone group.

In group II triton injection increased the LDL level to 174.8 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, LDL level was 45.55 mg/dl which was 3.8 times lower as compared to triton alone group.

In group II triton injection increased the VLDL level to 122.84 mg/dl. Whereas in Group III, simultaneous oral, administration of Amla seed extract in triton injected rats, VLDL level was 19.17 mg/dl which was 6.4 times lower as compared to triton alone group.

The other amla extracts (prepared in example 3 to 6) at 40 mg/kg were also able to decrease the cholesterol and triglyceride level but these were less effective than amla seed extract prepared in example 1. The standard drug Atorvastatin was also effective in lowering the cholesterol as well as triglyceride levels (Group VIII).

Example 21 Single Dosage Study for Evaluating Hypolipidemic Activity of Amla Seed Extract Compared with Other Amla Extracts Using Triton WR 1339 Induced Dyslipidemia Model

Forty eight male Albino rats (Sprague Dawley strain) weighing approximate 250-300 gm were selected for the study. The animals were kept in the animal house maintained at temp 24±2° C., 65% relative humidity and 12 hr light/dark cycle. The rats were acclimatized for two weeks and during this period they had access to standard pellet diet and water ad libitum. After two weeks of acclimatization, all the rats were fasted overnight before injecting Triton WR 1339 (Tyloxapol) and administration of test extracts/standard. The animals were divided into eight groups. Following treatment was given to overnight fasted rats:

Group I: Normal control (vehicle only) Group II: Triton WR 1339 (300 mg/kg, intraperitoneal) Group III: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla seed extract prepared as per example 1 (2.5 mg/kg, per oral) Group IV: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla extract prepared as per example 3 (2.5 mg/kg, per oral) Group V: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla extract prepared as per example 4 (2.5 mg/kg, per oral) Group VI: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla extract prepared as per example 5 (2.5 mg/kg, per oral) Group VII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Amla extract prepared as per example 6 (2.5 mg/kg, per oral) Group VIII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Atorvastatin (10 mg/kg, per oral)

The animals were deprived of food for next 24 hours but had free access to water ad libitum. After 24 hour of drug treatment 2 ml blood samples were collected from the retro orbital plexus. The blood was allowed to clot and then centrifuged at 3000 rpm for 10 mm and the serum was carefully drawn and collected into separate tubes. The serum was analyzed for total cholesterol triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) levels using auto-analyzer.

In this study, Amla seed extract (2.5 rag extract/kg of subject) was compared with other amla extracts made as in example 3 to 6 at the same dose level, i.e. 2.5 mg of extract/kg of subject.

Results indicated that before treatment the baseline value of total cholesterol, triglyceride, HDL, LDL and VLDL in all groups were comparable. Injecting Triton alone (Group II) significantly increased the total cholesterol level to 385.54 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, cholesterol level was 108.25 mg/dl which was 3.6 times lower as compared to triton alone group.

In group II triton injection increased the triglyceride level to 644.65 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, triglyceride level was 111.36 mg/dl which was 5.8 times lower as compared to triton alone group.

In triton alone group after triton injection, the ratio of HDL to total cholesterol was 0.15. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, the ratio of HDL cholesterol to total cholesterol was 0.42 which was 2.8 times higher as compared to triton alone group.

In group II triton injection increased the LDL level to 197.07 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, LDL level was 39.75 mg/dl which was 4.9 times lower as compared to triton alone group.

In group II triton injection increased the VLDL level to 128.93 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract in triton injected rats, VLDL level was 22.27 mg/dl which was 5.8 times lower as compared to triton alone group

The other amla extracts (prepared in example 3 to 6) at 2.5 mg/kg were able to decrease the cholesterol and triglyceride level to a certain extent only but these are not as effective as amla seed extract at same dose levels. The studies carried out indicate that the standard drug Atorvastatin though was effective in lowering the cholesterol as well as triglyceride levels (Group VIII) but less effective when compared with the amla seed extract.

Example 22 Antidiabetic Activity of Amla Seed Extract in Streptozotocin Induced Diabetic Rats

The Amla seed extract as prepared in example 1 was evaluated for antidiabetic activity in experimental rats. Male/Female albino wistar rats were maintained as per standard guidelines: housed in polypropylene cages, under 12 hour artificial light and dark cycles at a temperature of 24±2° C., given a standard pellet diet and water ad libitum. The animals were acclimatized to the animal house conditions for a week before beginning the experiment.

Diabetes was induced by injecting streptozotocin 35 mg/kg dissolved in 0.1 M citrate buffer of pH 4.5, intra-peritoneally. Five days after induction of diabetes (day 1 of the study), animals were fasted for 12 hours and the fasting blood glucose level (FBG) was estimated for diagnosing diabetic rats. Animals with FBG above 200 mg/dl were considered diabetic. The diabetic animals were randomly divided into three groups of six animals each.

Following table 5 shows the treatment schedule given to the respective group of animals for 28 days.

TABLE 5 Treatment schedule Groups Drugs administered Group I Vehicle for 28 days Group II Glibenclamide (0.5 mg/kg) for 28 days Group III Amla seed extract as per Example 1 (10 mg/kg) for 28 days Fasting blood glucose level and body weight of rats was measured initially and then at Day 7, Day 14, Day 21 and Day 28 of the study. The plasma CRP level was measured initially and then at Day 28 of the study.

As shown, in the results, a single ip injection, of streptozotocin increased the blood glucose level to very high level and made the rats diabetic. Treatment of diabetic rats with amla seed extract significantly lowered the blood glucose level in 28 days. That corresponds to a 2.7 times reduction, in tasting blood glucose level in diabetic rats as compared to baseline (Day 1) after administration of amla seed, extract for 28 days. Treatment with, glibenclamide also decreased the blood glucose level to nearly normal in 28 days. Body weight of diabetic rats treated with amla seed extract recovered significantly as compared to vehicle group. The CRP level decreased significantly in amla seed extract fed group but glibenclamide tailed to decrease the CRP level significantly as compared to initial CRP value. 28 days treatment with. Amla seed extract to diabetic rats decreased the CRP level 1.6 times than initial level.

Example 23 Hypolipidemic Activity of Amla Seed Extract in Cholesterol Fed Rabbits

The Amla seed extract as prepared in example 1 was evaluated for hypolipidemic activity in experimental rats. Male NZ white rabbits weighing 1.5-2.0 kg were used for the experiment. They were housed in a temperature-controlled, room (25±2° C.) in clean stainless steel cages with ‘12 h light and 12 h dark’ cycles and fed with, normal pellet diet and water ad libitum.

After the acclimatization period of 10 days, blood samples were collected from marginal ear vein of all the rabbits. The blood was allowed to clot and then centrifuged at 3000 rpm for 10 min and the serum was care tally drawn and collected into separate tubes. The serum was analyzed for total cholesterol, triglycerides, high density lipoproteins (HDL), low density lipoproteins (LDL) and very low density lipoproteins (VLDL) levels using auto-analyzer.

After taking baseline lipid profile the animals were divided into four groups comprising of six animals in each group. Following treatment was given to the animals for the three months:

TABLE 8 Treatment schedule Groups Drugs administered Group I Vehicle for 3 months Group II Cholesterol (100 mg/kg) + Vehicle for 3 months Group III Cholesterol (100 mg/kg) + Amla seed extract as per example 1 (10 mg/kg) for 3 months Group IV Cholesterol (100 mg/kg) + Atorvastatin (10 mg/kg) for 3 months

Blood samples were collected from all the rabbits after 3 months of treatment, and serum was analyzed for lipid profile. After blood collection the animals were sacrificed after injecting pentobarbitone and aorta was dissected out, washed with saline and preserved in 10% formalin for histopathology. The sections were cut using microtome and stained with heamatoxylin & eosin dye and mounted on glass slides. The slides were observed under microscope and aortic intima media thickness (IMT) was measured by histomorphometry.

Results show that, before treatment the baseline value of total, cholesterol, triglyceride, HDL, LDL and VLDL in all groups were comparable. Feeding cholesterol for three months increased the total cholesterol and triglyceride levels to very high.

Administration of Cholesterol alone (Group II) significantly increased the total cholesterol level to 219.81 mg/dl. Whereas in Group III, oral administration of cholesterol+Amla seed extract, total cholesterol level was 94.18 mg/dl which was 2.3 times lower as compared to cholesterol alone group.

In group II cholesterol administration increased the triglyceride level to 188.25 mg/dl. Whereas in Group III, oral administration of cholesterol+Amla seed extract, triglyceride level was 83.23 mg/dl which was 2.3 times lower as compared to cholesterol alone group.

In group III, administration of cholesterol+ Amla seed extract increased the HDL (good cholesterol) level significantly from a baseline value of 15.42 to 37.27 after 3 months treatment. That was a 2.4 times increase in the HDL cholesterol after 3 month treatment.

After cholesterol administration the cholesterol alone group showed a ratio of HDL to total cholesterol was 0.05. Whereas in Group III, oral administration of cholesterol+ Amla seed extract, the ratio of HDL cholesterol to total cholesterol was 0.39 which was 7.8 times higher as compared to cholesterol alone group.

In group II administration of cholesterol alone increased the LDL level to 170.66 mg/dl. Whereas in Group III, oral administration of cholesterol+ Amla seed extract, LDL, level was 40.26 mg/dl which was 4.2 times lower as compared to triton alone group.

In group II administration of cholesterol alone increased the VLDL level to 37.65 mg/di. Whereas in Group III, oral administration of cholesterol+ Amla seed extract, VLDL level was 16.65 mg/dl which was 2.3 times lower as compared to cholesterol alone group

Atorvastatin also decreased the total cholesterol, and triglyceride level significantly as compared to untreated control group hut amla seed extract was better especially in increasing the HDL level.

Moreover, administration of amla seed extract showed a 1.9 times reduction in the intima media thickness of aorta of rabbits as compared to untreated control group.

Example 24 Hair Fall Prevention and Hair Growth Promoting Activity of Amla Seed Extract in Humans Method:

10 human subjects suffering with alopecia and severe hair fall (as detected by a dermatologist) were randomly divided into two groups comprising of 5 subjects in each.

Group I—Amla seed extract group prepared as per example 1. Group II—Placebo group

Ail the subjects were prohibited to take any kind of medicines (oral or topical) having hair growth promotion like minoxidil, finasteride etc. for one month prior to the study initiation. The subjects of group I applied 5 ml coconut oil containing 5% amla seed extract twice daily on the affected area and also took 100 mg of amla seed extract capsules twice daily. The subjects of placebo group were given coconut oil (without amla seed extract) to be applied twice daily on affected area and were provided with placebo capsules to be taken twice daily. The treatment was continued for 3 months and observations were taken by a dermatologist before and after the study period. Length and thickness of randomly plucked five hairs from each subject was also determined.

Results:

The hairs of subjects treated with amla seed extract were shiny, lustrous and denser as compared to placebo group. The hair fail was almost arrested in the subjects treated with amla seed extract. In contrast, the subjects of placebo group observed hair fall at the same rate as it was before starting the treatment. The average length of hairs of subjects treated with amla seed extract was about 25% more than the subjects of placebo group. Thickness of the hairs was also about 20% more in amla seed extract group as compared to subjects in placebo group. Therefore, amla seed extract was helpful in decreasing the hair fall as well as in promoting hair growth. Amla seed extract also made the hairs lustrous and shiny.

Example 25 Hypolipidemic Activity of Amla Seed Extract Compared with Other Amla Extracts Using Triton WR 1339 Induced Dyslipidemia Model

Forty eight male Albino rats (Sprague Dawley strain) weighing approximate 250-300 gm were selected for the study. The animals were kept in the animal house maintained at temp 24×2° C., 65% relative humidity and 12 hr light/dark cycle. The rats were acclimatized for two weeks and during this period they had access to standard pellet diet and water ad libitum. After two weeks of acclimatization, all the rats were fasted overnight before injecting Triton WR 1339 (Tyloxapol) and administration of test extracts/standard. The animals were divided into twelve groups. Following treatment was given to overnight fasted rats:

Group I: Normal control (vehicle only) Group II: Triton WR 1339 (300 mg/kg, intraperitoneal) Group III: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by Ethyl acetate of methanol extract of Amla seed prepared as per example 1 (2.5 mg/kg, per oral) Group IV: Triton WR 1339 (300 mg/kg, intraperitoneal) followed, by wafer part of methanol extract of Amla seed prepared as per example 1 (2.5 mg/kg, per oral) Group V: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by ethyl acetate extract of Amla seed prepared as per example 2 (2.5 mg/kg, per oral) Group VI: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by powder of dried Amla seed prepared as per example 7 (2.5 mg/kg, per oral) Group VIII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by water extract of dried Amla seed powder prepared as per example 8 (2.5 mg/kg, per oral) Group VIII: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by methanol extract; of dried Amla seed powder prepared as per example 8 (2.5 mg/kg, per oral) Group XI: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by powder of dried Amla fruit prepared as per example 10 (2.5 mg/kg, per oral) Group X: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by water extract of dried Amla fruit powder prepared as per example 11 (2.5 mg/kg, per oral) Group XI: Triton WR 1339 (300 mg/kg, intraperitoneal) followed by methanol extract of dried Amla fruit powder prepared as per example 12 (2.5 mg/kg, per oral) Group XII: Triton. WR 1339 (300 mg/kg, intraperitoneal.) Followed by Atorvastatin (2.5 mg/kg, per oral.)

The animals were deprived of food for next 24 hours hut had free access to water ad libitum. After 24 hour of drug treatment 2 ml blood samples were collected from the retro orbital plexus. The blood was allowed, to clot and then centrifuged at 3000 rpm for 10 mm and the serum was carefully drawn and collected info separate tubes.

Results show that, before treatment the baseline value of total cholesterol, triglyceride, HDL, LDL and VLDL in all groups were comparable.

Injecting Triton atone (Group II) significantly increased the total cholesterol level to 288.18 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract, prepared, as per example 1 in triton injected rats, cholesterol level was 106.41 mg/dl which was 2.7 times lower as compared to triton alone group.

In group II triton injection increased the triglyceride level to 581.42 mg/dl. Whereas in Group III, simultaneous oral administration of Amla seed extract prepared as per Example 1 in triton injected rats, triglyceride level was 90.47 mg/dl which was 6.4 times lower as compared to triton alone group.

In triton alone group after triton injection the ratio of HDL to total cholesterol was 0.15.
